This paper develops a measurement method which can be used for precisely measuring the indexing precision and the movement parameters of space indexing cam rnechanisms. It also introduces the principle of the systein to realize the real-time measurernent for the dynamic properties of the mechanisms with the applicathion of mechano-electronic intergration and automatic control technology.
Spatial indexing of high-dimensional data based on relative approximation
Using a detailed cycle-accurate energy estimation framework and four different datasets, this paper examines the pros and cons of three previously proposed spatial indexing alternatives from both the energy and performance angles.
A novel approach to operation with a structure for spatial indexing of extended objects shaped as R-trees is considered.
After providing the description of the algorithms we to discuss the improvement that spatial indexing techniques can bring to them.
A common example is the creation of spatial indexing structures to support fast searches on geographical or geometric data.
Firstly, the spatial data is stored as raster data with space index, so the image processing can be done directly on the GIS data that is stored hierarchically according to the distinguishing precision.
For these systems we introduce a uniform differential time index and a differential space index.
It is known that a k-strongly parabolic surface in Euclidean space (index of relative nullity is at least k) inherits a k-strongly parabolic metric (index of nullity is at least k).
Amongst them are vector-space index search and fuzzy noun phrase index-based search.
Three metric space index structures are discussed in Section 2, followed by an introduction to our workloads and experimental results in Section 3.
In this paper,on the basis of the engaic principle of the spatial curved surface,the roller gear indexing cam drive mechanism is system- atically studied by using the rotating metrix operators and differential geometry theory.The cam profile equation,engagic equation,and a series of the computing foumulas such as the pressure angle.Curvature information of roller gear indexing cam drive mechanism are derived.Finally,the con- dition for undercutting is given.
